  • the invention further relates to a station or plant for treating workpieces, in particular vehicle wheels, comprising a conveying system by means of which the workpieces may be conveyed through the station.
  • spindle conveyers of the type mentioned at the outset in particular vehicle wheels are conveyed through successive treatment stations of a coating plant in which, in a plurality of treatment steps, the vehicle wheels are provided with a surface coating.

  • the first and the second workpiece spindles are arranged behind one another, as seen in the direction of transport, in the first rotary position of the pair of workpiece spindles, and next to one another, as seen in the direction of transport, in the second rotary position of the pair of workpiece spindles.
  • transport carriages include a coupling device by means of which the running gear may be detachably coupled to an endless drive means
  • known and established drive system may continue to be used.
  • Drive chains have in particular proved their worth as endless drive means.
  • the endless drive means carries along entrainers which cooperate with a coupling element of the coupling device, wherein this coupling element may be moved between a coupled position, in which one of the entrainers of the endless drive means can abut against the coupling element, and a released position, in which the entrainers of the endless drive means can be guided past the coupling element without coming into operative contact.
  • the transport carriages in the buffer zone may be separated from the endless drive means and remain there until they are fed in to the process downstream.
  • the transport carriages may travel in closer succession to one another than in a conveying zone and form a type of buffer train in the buffer zone.
  • the minimum spacing may be predetermined favourably by arranging the release unit at the free end of a spacing arm of the transport carriage.
  • the minimum spacing by which a trailing transport carriage is separated from the drive means may be adjusted by way of the length of this spacing arm.
  • spindle conveyor is constructed in the manner of a floor track, as is indeed the case with current known spindle conveyors.
  • the spindle conveyor may be constructed in the manner of an overhead track.
  • the most important components of the conveyor such as rails, drive means and transport carriages, may be arranged above the workpieces, with the result that soiling that occurs during workpiece treatment and may fall down cannot come into contact with the conveyor components and soil them.
  • the object mentioned above may be achieved in that the conveyor system is a spindle conveyor having some or all of the features mentioned above.
  • FIG. 1 shows a side view of a detail of a floor-guided spindle conveyor having a carrying rail, wherein a transition between a buffer zone and a conveying zone of the spindle conveyor is shown in a direction of transport, and two transport carriages in a buffer configuration are located in the buffer zone and a transport carriage in a conveying configuration is located in the conveying zone;

  • FIGS. 1 and 2 show, respectively in side view and in a view from above, a detail of a floor rail system 10 of a conveying system in the form of a floor-guided spindle conveyor 12 for conveying workpieces.
  • the workpieces are illustrated as vehicle wheels 14 , only some of which bear a reference numeral.
  • the vehicle wheels 14 are conveyed in a direction of transport 16 through a plant 17 for the treatment of the vehicle wheels 14 which includes the spindle conveyor 12 .
  • the rail system 10 has a single track and includes a carrying rail 18 which is anchored to the floor and includes a lower guide profile 20 and, running vertically above it, an upper guide profile 22 , between which there remains a free space forming a coupling region 24 .
  • an endless drive chain 28 which in the form of an endless drive means carries along a plurality of entrainers 30 .
  • the entrainers 30 project upwards from the endless drive chain 28 into the coupling region 24 of the carrying rail 18 .
  • a running gear 32 of a transport carriage 34 which for this purpose carries load-bearing rollers 36 , by means of which the running gear 32 runs on a running surface (not itself provided with a reference numeral) of the upper guide profile 22 .
  • the running gear 32 bears a plurality of guide rollers 38 which stabilise the running gear 32 and hence the transport carriage 34 to prevent both tilting in a direction of transport 16 and tilting to the side, as is known per se.
  • the rollers and guide rollers 36 , 38 are in particular readily visible in FIG. 6 and, for the purpose of clarity, are moreover only provided with reference numerals there.
  • the running gear 32 carries a coupling device 40 , part of which projects downwards into the coupling region 24 of the carrying rail 18 , and by means of which the transport carriage 34 may be coupled to and released from one of the entrainers 30 of the drive chain 28 . This will be discussed in more detail below.
  • the running gear 32 carries along a carrying device 42 for the vehicle wheels 14 .
  • This carrying device includes a horizontal rotary cross piece 44 , which is connected to an axial bearing 50 in the middle between its opposing ends 46 , 48 , such that it cannot rotate in relation thereto, wherein this axial bearing 50 , when the spindle conveyor 12 is in operation, projects downwards from the rotary cross piece 44 .
  • the running gear 32 bears the axial bearing 50 such that the latter may rotate about an axis of rotation 52 which, when the spindle conveyor 12 is in operation, extends vertically.
  • the longitudinal axis of the axial bearing 50 coincides with the axis of rotation 52 .
  • the rotary cross piece 44 On its side remote from the axial bearing 50 , the rotary cross piece 44 carries at its first end 46 a first workpiece spindle 54 a and at its opposing, second end 48 a second workpiece spindle 54 b , which are of the same construction and are borne such that they may rotate about their longitudinal axis. Both workpiece spindles 54 a , 54 b point upwards when the spindle conveyor 12 is in operation, and extend parallel to one another.
  • the workpiece spindles 54 a , 54 b form a pair 56 of workpiece spindles and each have at their free end regions 58 a , 58 b a workpiece receiver, which in the present exemplary embodiment takes the form of a support plate 60 for the vehicle wheels 14 , as is known per se.
  • the spacing between the two workpiece spindles 54 a , 54 b along the rotary cross piece 44 is adapted to the mode of operation of the treatment plant 17 in which the vehicle wheels 14 are to be treated.
  • first and the second workpiece spindle 54 a , 54 b are secured on the rotary cross piece 44 such that they are stationary and at an invariable spacing from one another. This spacing may for example be predetermined by the equipment used for handling the vehicle wheels 14 .
  • the two workpiece spindles 54 a , 54 b may also be mounted on the rotary cross piece 44 such that they are displaceable and lockable in an operative position, with the result that the spacing between the workpiece spindles 54 a , 54 b along the rotary cross piece 44 may be adjusted.
  • the pair 56 of workpiece spindles is able to adopt four positions which succeed one another in a direction of rotation and are offset by 90° in each case, wherein each two rotary positions that are offset by 180° have the same function and each define an operational configuration of the transport carriage 34 :
  • the transport carriage 34 there is a conveying configuration of the transport carriage 34 , in which the workpiece spindles 54 a , 54 b adopt as the first rotary position a conveying position in which they are arranged behind one another as seen in the direction of transport 16 .
  • either the first workpiece spindle 54 a or the second workpiece spindle 54 b can adopt the front position, as seen in the direction of transport 16 .
  • the pair 56 of workpiece spindles of the transport carriage 34 shown on the far left adopts the conveying position, with the result that the vehicle wheels 14 are conveyed behind one another, as seen in the direction of transport 16 .
  • the transport carriage 34 there is a buffer configuration of the transport carriage 34 in which the workpiece spindles 54 a , 54 b adopt as the second rotary position a buffer position in which they are arranged next to one another as seen in the direction of transport 16 .
  • either the first workpiece spindle 54 a or the second workpiece spindle 54 b can adopt the left-hand position, as seen in the direction of transport 16 .
  • the pairs 56 of workpiece spindles of the two transport carriages 34 shown on the right adopt this buffer position, with the result that the vehicle wheels 14 are conveyed next to one another, as seen in the direction of transport 16 .
  • the carrying device 42 may be stabilised, in the conveying position or the buffer position, by means of a holding device 66 to prevent unintentional rotation.
  • a portion of the axial bearing 50 may have a square cross section, with resilient webs abutting against two opposing outer surfaces of this portion. These resilient webs are able to hold the axial bearing 50 and hence the carrying device 42 in the adopted conveying or buffer position without the action of an external force.
  • the retaining force of the resilient webs has to be overcome. Because of the square cross section of the axial bearing 50 , when the latter is rotated the resilient webs are first bent apart until, after rotating through 90°, they abut again against two opposing outer surfaces of the portion of the axial bearing 50 that is square in cross section.
  • the rail system 10 of the spindle conveyor 12 includes a plurality of conveying zones 68 and a plurality of buffer zones 70 , with a buffer zone 70 connecting two conveying zones 68 to one another in each case.
  • the buffer zones 70 for example take the form of a portion of a secondary rail section which runs alongside a main rail section and is connected thereto by way of points units (not shown).
  • the transport carriages 34 are driven along a main rail section of this kind for example by means of the endless drive chain 28 , which is guided around in a circle.
  • the term “conveying zone” is to be understood to mean any region of the rail system 10 which does not serve as a buffer zone, and in which the transport carriages 34 adopt their conveying configuration.
  • the points units, or rail portions leading to the carrying rail 18 in the buffer zone 70 should also be considered a respective conveying zone 68 .
  • the endless drive chain 28 moves at the same speed in the buffer zone 70 as in the conveying zone 68 .
  • the transport carriages 34 may be moved at different speeds in the conveying zone 68 and the buffer zone 70 .
  • a transition 72 is shown between a buffer zone 70 and a conveying zone 68 which is downstream of the buffer zone 70 as seen in the direction of transport 16 .
  • FIG. 5 shows a transition 74 between a conveying zone 68 , which is upstream of the buffer zone 70 as seen in the direction of transport 16 , and this buffer zone 70 .
  • the transport carriages 34 In the conveying zones 68 , the transport carriages 34 occupy their conveying configuration, and in the buffer zones they occupy their buffer configuration.
  • the transport carriages 34 When the transport carriages 34 are moved out of the conveying zone 68 and into the buffer zone 70 or back out of the buffer zone 70 and into the conveying zone 68 , the pairs 56 of workpiece spindles are rotated out of the conveying position and into the buffer position, or out of the buffer position and into the conveying position.
  • the rotary cross piece 62 of the carrying device 42 for the transport carriages 34 cooperates with actuating elements in the form of actuating pins 76 , of which in each case one is arranged laterally alongside the carrying rail 18 , at the transition 72 or 74 between a conveying zone 68 and a buffer zone 70 of the rail system 10 .
  • the actuating pins 76 are positioned and project upwards from the floor far enough to abut against the respectively laterally projecting entraining lug 64 of the rotary cross piece 62 of the transport carriage 34 and to rotate the latter through 90° if a transport carriage 34 moves past an actuating pin 76 in the direction of transport 16 .
  • the carrying unit 42 is then rotated through 90° about the axis of rotation 52 .
  • the transport carriages 34 may be parked according to the first-in first-out principle, and for this purpose they must be separated from the drive chain 28 in the buffer zones 70 . As mentioned above, this is made possible by the coupling device 40 . Moreover, the coupling device 40 allows the transport carriages 34 to be moved closer to one another in the buffer zones 70 than in the conveying zones 68 , where they maintain a conveying spacing which is predetermined by the spacing between two entrainers 30 of the drive chain 28 .
  • the rocker member 70 forms a coupling element 82 which, on pivoting of the rocker member 78 , can be moved between a lower coupled position and an upper released position.
  • the coupling element 82 projects far enough into the coupling region 24 of the carrying rail 18 for an incoming entrainer 30 of the drive chain 28 to abut against the front rocker member 78 , as a result of which the transport carriage 34 is carried along by the drive chain 28 .
  • the coupling element 82 In the released position, the coupling element 82 is moved upwards out of the coupling region 24 of the carrying rail 18 far enough for the entrainers 30 of the drive chain 28 to be able to pass underneath the coupling device 40 without coming into operative contact with the coupling element 82 . This means that in some cases there may be a light contact with the components but this does not result in the transport carriage 34 being carried along by the drive chain 28 .
  • the coupling device 40 also includes a rear rocker member 84 , as seen in the direction of transport 16 .
  • This rear rocker member 84 is also borne on the running gear 32 such that it may pivot about a horizontal pivot axis that extends perpendicular to the direction of transport 16 .
  • the rear rocker member 84 follows the pivotal movement of the front rocker member 78 , with the result that it frees the path for the entrainers 30 of the drive chain 28 when the coupling element 82 adopts its released position.
  • the rear rocker member 84 projects into the coupling region 24 of the carrying rail 18 far enough to flank a corresponding entrainer 30 of the drive chain 28 .
  • the geometry and dimensions of the separating ramp 86 are adapted to the front rocker member 78 such that the coupling element 82 thereof is then raised into the released position, as a result of which the transport carriage 34 is separated from the drive chain 28 and the entrainers 30 thereof run underneath the coupling device 40 .
  • the separating ramp 86 in its separating position, serves as a barrier to the transport carriage 34 , and prevents it from moving in the direction of transport 16 .
  • each transport carriage 34 includes a spacing arm 88 which extends in the direction opposed to the direction of transport 16 and carries at its free end a buffer ramp 90 which similarly has a roll surface which is downwardly inclined as seen in the direction of transport 16 .
  • This buffer ramp 90 forms a release unit and cooperates with the front rocker member 78 of a trailing transport carriage 34 in the same way as the separating ramp 86 of the buffer zone 70 .
  • the coupling device 40 of the rising transport carriage 34 is uncoupled from the drive chain 28 , and the two transport carriages 34 form a detached buffer train 92 , which can be seen in FIGS. 5 and 6 and in which the individual transport carriages 34 are not coupled to one another. If this last is to happen, in a modified arrangement for example corresponding coupling catches are provided which detachably connect two adjacent transport carriages 34 to one another.
  • the minimum spacing between two adjacent transport carriages 34 in this buffer train 92 is determined by the length of the spacing arm 88 of each transport carriage 34 , and is smaller than the spacing between two successive entrainers 30 of the drive chain 28 .
  • the now succeeding transport carriage or carriages 34 also move(s) into the conveying zone 68 .
  • the separating ramp 86 is once again put in its separating position such that the buffer train 92 can be formed in the buffer zone 70 again.
  • FIG. 7 shows by way of example, as a modified arrangement, a spindle conveyor 94 which is constructed in the manner of an overhead track conveyor.
  • a spindle conveyor 94 which is constructed in the manner of an overhead track conveyor.
  • components corresponding to those of the spindle conveyor 12 in FIGS. 1 to 6 bear the same reference numerals.
  • the carrying rail 18 is arranged at a level above the floor by means of beam constructions which are not themselves shown.
  • the spindle conveyor 94 may for example be constructed in the manner of a so-called power and free conveyor, as is known per se.
  • the carrying device 42 here includes a perpendicular carrying strut 96 which is coaxially connected to the axial bearing 50 .
  • the carrying strut 96 At its lower end, remote from the axial bearing 50 , the carrying strut 96 carries a U-shaped spindle structure 98 which again predetermines a pair 56 of workpiece spindles having a first workpiece spindle 54 a and a second workpiece spindle 54 b.
  • the transport carriages 34 are to adopt their buffer configuration in a conveying zone 68 and their conveying configuration in a buffer zone 70 . This may be necessary for example at the transition from a horizontal portion to an ascending portion or from a descending portion to a horizontal portion of the carrying rail 18 .
  • actuating pins 76 which are positioned accordingly and in addition in a conveying zone 68 or buffer zone 70 .
  • actuating pins 76 which are positioned accordingly and in addition in a conveying zone 68 or buffer zone 70 .
